To all whom t may. concern:

Be it known that I, SAMUEL R. HNT, J r.,

a citizen orI the United States, residing-at Peabody, in the county of Marion, Stateof Kansas, have invented certain new and useful improvements in Adjustable Bedadapted to support bed-springs of woven` Awire mattress forni, and has for one of its objects to improve the construction and increase the eliiciency and utilityr of devices of this character.

Another object of this invention is to provide a simply constructed device of this character whereby the web or mattress hold" ing portions of' bed-springs are supported l vmember 11 are two side rails 12--13, preferably formed from sections of gas piping from sagging, and the'strain of the springs adjusted.

Vil-lith, these and other objects in view the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the inven tion, Figure 1 is a plan view of the improved device with `the mattress holding.

portion partly broken away, to show. the supporting devices. Fig.`2 is a. side view of the same. Fig.v 3 is an enlarged, sectional' detail of one corner of the device, illustrating the construction. Fig.v 4r is aper-` spective view,-enlarged of -a portion of one of the yielding supporting bars.

The improved device comprises end menu lbers 10-11, one of which will be arranged at the head of the bed,.and for the purpose of illustration the member 10 vwill be referred to as the head member, and-the meinber 11 as the foot member.

'Rigidly connected at oneend Ato the Jfoot and arranged to` tover j coremembers 1st-15, the latter fitting through the 'toot member 11 and entering the rail members 12-13, and secured thereto by rivets 16-17' or other suitable fastening devices. j Connected to the inner face of theIhead 4'having and 'slidably engaging in the adjacent pory tion of the rail member 12, and the bracket 19 provided with a similar stud -21 slidably engaging in the adjacent portion of the ,rail 13.

Connected to the rail 12 adjacent to the stud 20 is a sleeve or collar 22 having a threaded projection 23, while a similar collar 24k is connected to the rail 13 and provided wit-h a threaded projection 25. Fit.- ting through the projection 23 is an adjusting screw 26 and likewise tting through the projection 25 isan adjusting screw 27, the outer ends of the adjusting screws bear'- ing respectively. against Athe brackets 18-19, as shown. The adjusting screws are prof vided with square ends to receive a wrench to enable them to be rotated. By this arrangement. it will be obvious that the head member 10 may be adjusted farther from' or nearer to the :toot member -11 by simply' rotating the. adjusting screws.

The woven wire web is connected i-n the usual manner to' the members lll- 11, und.

when thus arranged it will be obvious that the web may be strained to any required extent by simply operating the adjusting screws. 1

The improved 'device is provided with means for supporting the web or the bed, to prevent sagging, and these supporting devices are connected to the, members 10--11,y

and will now be described.

Fitting through the :members 10-11 are eye bolts Qt- 29, the eve bolts preferably spaced at uniform distances apart, andia'rranged in pairs, there being an equal num` ber of pairs in each of' the head and test ineinbers. Located pposite eaclipair of the eye bolts is a. bar 3 having a central aperture' to receiveV arod 31, the rod being threaded at one end to receive a nut 32 bearing against the member 30, and with an eye 33 at the other end to receive a bail or yoke member 34. The terminals or" the members 30 are coupled by springs 35436 'to the yeye, bolts 2S-29. The inner ends of the bails 34 are. coupled respectively to longitudinal bars 37,`the latter being preferably formed from sections. of T bars, asshown. One set of the bars V30 and the rods 31 `tegether with thesprings 354-36. 'and baile V34 will be arranged ateaclvend ofthe device, the T members 37 being provided at,A each end with one of the bails, as shown;l 'Byths' simple means the. T members are supported f flexibly in position, and bear against the under side of the web portion of the bed, and support the same, and etl'ectually prevent sagging when in use, and by operating the nuts 32 any required degree of tension maybe imparted, and any slaclrness taken up in the same manner. The springs 35-36 will be of sufficient strength to withstand the strains to which they will be subjected, and will holdtiie web in position. y

Any required number of the plates 37 and their associated parts may-be employed, but generally three pairs of the plates will be sutiicient for an ordinary sized bed, but it will be understood that any required number may be employed.

The foot and end members 10-11 will generally be ofwood ot the ordinary size of the end members of woven wire mattresses, but may be of metal it' preferred, while the remaining parts of the device are entirely of metal.

' Vliat is claimed, is v l. In a device of the-class described rigid endmembers, a web connected to-the end members, tubular side rails connected at one end to one of said end members, studs extending` from the other end member and slidably engaging in the side rails, adjusting screws carried by said rails and bearing against the adjacent end member, bars having central apertures, tension springs between said bars and end members, rods threaded at their outer ends and extending through the apertures of said bars, nuts engaging the threaded portions of said rods and bearing upon said bars, yQlres swinging from the inner ends of said rods, and plates ceases connecting `Lhe Vfree ends of said yokes and bearing beneath said web.

2. In a device of the class described rigid end members, a web connected to the end members, side rails connecting" said end members, means for applying strain between vsaid end members and web, bars having central apertures, tension springs between said bars and end members, rods threaded at one bar located opposite each pair of eye bolts, tension springs connected between said bars and eyeb'olts, a threaded rod extending through each bar aperture, an adjusting nut engaging each rod and bearing upon the adjacent bar, a yoke swinging from each ro'd, and plates swinging between the inner ends of the yokes.

In testimony whereof, I aiiix my signature, in presence of two witnesses.
